Got this iconic beat machine in town fora fair price. Battery needed a replacement and all of the 30 push buttons were cleaned with isopropanol. Fader 8 is still flakey. After that i experimented with the ssm2044 chip and came up with an external control box for both of thi filters. Cutoff 1,2 Reso 1,2 Env. Depth 1,2

I found this broken at a local shop and fixed some problems. First there was the powersupply broken and needed replacement (+15, -15, +5 Volt) Next up it was not possible to load the OS via the floppydrive (are all the included disks failed?) so i replaced it with a gotek+display+rotary. Now it works fine and got thousands of sounds on USB;)

After decades i was able to aquire this gem in my hometown. Switchboard and transistors on the mainboard for driving LEDs were faulty and some switches needed a replacement. I decided to modify it non destructive as possible with the following mods i did to the RC-808 and the yocto clone alteady. BD tune SD tune, snappy decay CL/Rim tune CP reverb Noise level Metal noise overdrive Metal tune Noise/Metal Hat switch OH CH choke off switch CYM short decay switch I made the same Mod for my friend Break…read more

What drove me crazy (together with Deborah and Daniel as well, thx for your help my friends!) was that Studer did not really document their special pinout for the serial connector. more info…read more

In October 2017 G and eorge Lazenbleep and Medallion Man headed to Dresden, for the Circuitcontrol festival, a week of hacking, soldering and live performance. In the first of a series of articles from the festival, we met up with Jacob Korn. I won’t talk about his recording career, as I’m much more interested in his work as an engineer. We met 4 years ago in Dresden, and I remember spending an evening together geeking out about an 808 kick drum circuit I built. We talked about his 909 at the time, and I…read more

Rat Life Records presents Serial Error a Project by Credit 00, Jacob Korn & Sneaker. This outfit was brought to life in 2013 when Red D called for some New Beat style tracks for his “Our Beat Is Still New” Compilation. Flying a bit too low under the radar ever since Rat Life decided to reissue Drum Abuse on a Super Sound Maxi Single. The Track was made in Jacob Korn’s headquarter studio / synthesizer museum. The task distribution was hit quickly: Jacob squeezing the acid out of his huge…read more
